In the Original Investigation titled, “A New Equation for Calculation of Low-Density Lipoprotein Cholesterol in Patients With Normolipidemia and/or Hypertriglyceridemia,”1 which published online February 26, 2020, there were errors in Figure 1A, Figure 3A, and Figure 4A and B. In Figure 1A, placing “Mean (SD)” in front of the root mean square error (RMSE) and in front of the correlation coefficient (R2) was incorrect because the RMSE and R2 values are from the validation data set and the corresponding values in parentheses are from the training set. These are not mean (SD) values, and therefore “Mean (SD)” should be removed from both places. In Figure 3A, “Equation 1” should be changed to “Equation 2.” In Figure 4A, the triglyceride interval from 600 to 699 mg/dL on the x-axis should be changed to 600 to 799 mg/dL. In Figure 4B, the triglyceride interval from 400 to 799 mg/dL on the x-axis should be changed to 600 to 800 mg/dL. This article was corrected online.
